They basically do super low budget rip offs of whatever "big movie" is currently coming out, typically released just a day or two before the actual movie.

The titles are basically almost the same just slightly differentTransmorphersSnakes on a TrainMonster (instead of Cloverfield)Pirates of Treasure Island (starring Lance Henriksen. No really)and on and on

It's worth it just to watch the trailers. And most of the movies have trailers.
